Developmental Psychology
- What shapes the way we change over time?
- Focus on psychological changes across the entire life span
- Every area of psychology can be looked at from this perspective - biological development - social development - (^) cognitive/perceptual development - (^) personality development
Fundamental Issues: Is Development Continuous?
- Development means change; change can be abrupt or gradual
- Two views of human development - stage theories: there are distinct phases to intellectual and personality development - continuity: development is continuous
Dominant and Recessive Genes
Genotype—underlying genetic makeup
- Phenotype—traits that are expressed
- Dominant genes—will always be expressed if present
- Recessive genes—will not be expressed unless they are in a pair
Physical and Psychological
Development Related
Physical development begins at conception
- Physical maturity sets limits on psychological ability - visual system not fully functional at birth - language system not functional until much later
- Prenatal environment can have lifetime influence on health and intellectual ability
Prenatal Development
- Conception—when a sperm penetrates the ovum
- Zygote—a fertilized egg
- Germinal period—first two weeks after conception
- Embryonic period—weeks three through eight after conception
- Fetal period—two months after conception until birth
12 week fetus
18 week fetus
24 weeks (6 months)
28 weeks (7 months)
